It is taking a considerable amount of time to optimize a movie. When I check the resources on the server I find that it is only using only 1 core of the 12 CPU cores available. Has anyone seen this problem and know a fix? Thanks
Plex does not use multiple cores when optimizing. Instead of using Plex, you should use ffmpeg or Handbrake and make optimized versions yourself - you’ll be much happier with the results.

Not entirely true, from my own experience. Plex can (and has) used more than one core during an Optimize, depending on what the source codec is. There are a couple of codecs that can’t use more than one core. (VC-1 and H265 depending on the CPU, springing to mind.)
When I optimize H264 to a lower bitrate I get speeds only slightly less than what I get during an “on demand” transcode session. For my own use case, this is usually more than sufficient.
Ah yes, thanks for correcting me.
